Prince Harry and Ed Sheeran have teased something special in anticipation for World Mental Health Day on Thursday (October 10).

Earlier today, the Instagram account for the Duke and Duchess of Sussex shared a video teaser for a collaboration between the two in honor of the upcoming holiday. In the clip, Sheeran 28, is seen knocking on the royal's door, to which Prince Harry, 35, answers and says: "It's like looking in the mirror." From there, the singer asks, "Do you mind if I band cameras in?" and Harry agrees, saying, "Of course, yeah, come on it." "Come soon...," the caption for the post reads, alongside the #WMHD hashtag.

Avid Royal followers believe that the video was shot at the residence of Prince Harry's cousin, Princess Eugenie, as the background of the clip shows a wedding photo hanging on the wall. Some have guessed that the shot is of her bridal gown, which is sightly visible in the clip. She lives in Ivy Cottage at Kensington Palace with her husband, Jack Brooksbank.

Even without details of the collaboration, it's well known how important mental health advocacy is to Prince Harry. In fact, a few days ago, he teamed up with Duchess Meghan, Duchess Kate, and Prince William to narrate a PSA in promotion for the Every Mind Matters service, which gives people resources to support their mental well-being.
